Abstract：
Based on the analysis of the structural characteristics of the spindle box parts of a certain machine tool,the sand mold casting process scheme was preliminarily determined,and the casting process scheme of the spindle box was numerically simulated by ProCAST software.Through the analysis of temperature field,solidification process and shrinkage cavity and porosity,and the optimization measures such as reasonable setting riser and chill,the optimum casting process scheme of spindle box casting was determined.The results show that the filling and solidification process of spindle box castings is reasonable and the defects of shrinkage cavity and porosity are effectively avoided when the medium enlarge runner system is used 1:1.4:1.2(Aingate:Aruuner:A sprue),the pouring temperature is 1370℃ and the pouring speed is 5.7 kg/s.
